Gigaopto's GTS-L13B1-10DI is a high performance module transceiver for long-range data communication and interconnect applications which operates at 25.78Gb/s up to 10km fiber distance over single mode fiber(SMF) with duplex LC receptacle.

The 25G SFP28 LR transmitter section uses a 1310nm multiple quantum well DFB laser and is a class 1 laser compliant according to International Safety Standard IEC 60825. The receiver section uses an integrated InGaAs detector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC, and featuring with Gigaopto’s proven circuit, this SFP28 LR provides reliable long life, high performance and consistent service.

It is with the SFP+ 20-pin connector to allow hot plug capability. Digital diagnostic functions are available via an I2C. It has built-in clock and data recovery (CDR).

Featuring an industrial grade operating temperature range from -40 to 85°C (-40 to 185°F),this 25G LR transceiver is suitable for both outdoor and indoor deployments.




All Gigaopto’s transceivers are standards-based and MSA (Multi-Source Agreement) compliant, and rigorously tested and coded in our own facilities to ensure the highest level of performance. We conduct 100% application testing under end-use conditions.
